Have a HP i3-12100 desktop PC running Win11 Home. Purchased 7 months ago. Connected to monitor via a HDMI cable.
Yesterday, when I did a power on boot, the keyboard backlight went on/off as it normally does but then the monitor screen stayed black. Then the monitor popped a message saying that "No HDMI signal from the computer". Held the power on button in for 10 seconds and the PC powered off. Tried to boot again but same thing happened. Pulled the power plug for 10 seconds and plugged back in. Did a power on boot and same thing happened.
On the next power on boot, I tapped the F10 key and the PC booted into the BIOS. Was able to view the BIOS settings using the USB keyboard for navigation. When I exited the BIOS, it did not boot into Win11 and the screen stayed black. "No HDMI signal from the computer" message popped up again.
Booted into BIOS again but this time when exited the BIOS, Win11 booted up. Everything in Win11 worked normally. I left the PC on overnight and this morning Win11 is still running normally.
ANY IDEAS?
PS: Normally when I press the power on button momentarily, there is about 1 second delay, then the power on LED comes on and then the PC boots into Win11. When the problem was happening, when I pressed the power on button momentarily, the power on LED came on immediately. Not sure why.
